IMPROVED LAP-BOARD.

Swcilica'rion forming part of Letters Patent No. {02,530, dated May R, 1r70.

To all whom it may concern:

Be it known that I, "WILLIAM F. GAMMEL, of Elizabeth, in the county of Union and State New Jersey, have invented a new and useful Improvement in Lap-Boards; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same7 reference being had to the accompanying drawings, forming part of this specification.

Figure 1 is a top view of my improved lapbroad, showing in dotted lines the position of the work-box and the legs folded up. Fig. 2 is avertical section of the same,'taken through the line x x, Fig. 1, and showing the work-box opened out and the legs extended in position for use.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of lap-boards, so as to make them more convenient and effective in use; and it consists in the construction and combination of the board, hinged legs, and pivoted box With each other, as hereinafter more fully described.

A is the board,which is made broader than has heretofore been practicable, and the edge next the operator is recessed or concaved, as shown in Fig. 1, to receive the body of the operator, and thus make a greater portion of the To the under tached cross-strips c', to keep the board from warping. The inner or concaved part of the boardA is designed to rest upon the lap of the user, and its outer part is designed to be supported by legs B, which are designed to be hinged to the cross-bar a near their outer ends, as shown in Fig. 2, so that when not required for use they may be folded up, as shown in dotted lines in Fig. 1, for convenience of storage.

C is a box, to one end of which is rigidly and rmly attached an arm, c', which extends along the under side of the board A, to which it is pivoted, the pivoting screw passing through the said arm at some distance fromv its end to enable it to more firmly support the said box. rIhis construction enables the box to be conveniently turned out into the position shown in Fig. 2, to obtain access to the interior of the said box, or to be turned in beneath the board A, as shown in dotted lines in Fig. 1.

Having thus described my invention, I claim as new and desireto secure by Letters PatentrIhe lap-board consisting of board A, crossstrips c, hinged legs B, box C, and arm c', all constructed, arranged, and adjusted together as and for the purpose described.

rIhe above specification of my invention signed by me this 23d day of February, 1870.

WILLIAM F. GAMMEL.
